Nano bamboo fiber dry-mixed mortar with high tensile adhesive strength and preparation method of nano bamboo fiber dry-mixed mortar
The invention belongs to the technical field of constructional engineering, and relates to nano bamboo fiber dry-mixed mortar with high tensile adhesive strength and a preparation method thereof. The nano bamboo fiber dry-mixed mortar is prepared from the following components in parts by weight: 25 to 50 parts of cement base material, 60 to 65 parts of inorganic fine aggregate, 5 to 8 parts of mineral admixture, 2 to 5 parts of graphene modified nano bamboo fibers, 0.1 to 0.3 part of methyl cellulose, 1 to 6 parts of latex powder, 0.2 to 0.4 part of retarder, 0.02 to 0.1 part of polyaniline and 0.2 to 0.3 part of defoaming agent. According to the dry-mixed mortar provided by the invention, the graphene modified nano bamboo fibers are added, so that dust and small particles in the stirring process are effectively adsorbed, and dust raising is avoided; in the forming process, a firmer and more stable network structure is constructed by utilizing the flexibility and better surface and interface energy of the ball-milled graphene modified nano bamboo fibers with low crystallinity, the tensile strength and binding power of the dry-mixed mortar are greatly improved, and remarkable economic benefits and environmental benefits are achieved.
本发明属于建筑工程技术领域，涉及一种高拉伸粘结强度的纳米竹纤维干混砂浆及其制备方法。其技术要点如下：按照重量份数计算，包括如下组分：水泥基料25～50份、无机细骨料60～65份、矿物掺合料5～8份、石墨烯改性纳米竹纤维2～5份、甲基纤维素0.1～0.3份、乳胶粉1～6份、缓凝剂0.2～0.4份、聚苯胺0.02～0.1份和消泡剂0.2～0.3份。本发明提供的干混砂浆，通过石墨烯改性纳米竹纤维的加入，对搅拌过程中的灰尘和小颗粒进行有效吸附，避免扬尘；在成型过程中，利用球磨后结晶度低的石墨烯改性纳米竹纤维的柔韧性以及更好的表界面能构建更加牢固稳定的网络结构，大幅提高干混砂浆的拉伸强度和粘结力，实现显著的经济效益和环境效益。
